ROTARY GANG PLOW.

Application filed November 27, 192.5. Serial No. 71,825.

The object of this invention is to provide a new and improved form of arotary gang plow. Another object. of the invention is to provide amachine by which the plows are rotated by engine power while the machineis drawn forward by horses.

Another object of the invention is to provide a new and improved form ofpower transmission between the engine and the rotating gang plow.

Another object is to provide for the lifting of the plow so as to avoidobstacles and otherwise protect against serious damage that might becaused by collision with obtacles. These and other objects of theinvention will be fully illustrated in the drawing, described in thespecification and pointed out in t-he claims at the end thereof.

In the drawings:

Figure 1 is a top plan view of the plow.

Figure 2 is a side elevation thereof.

Figur-e 3 is a detailed perspective view of one of the plow shares andthe method of mounting it, the share being shown in seci' tion,

are connected together by suitable cross bars 4, 5, (i and 7 which arejust loiip; enougli to connect the sills. A little back of the center ofthe frame is placed a long cross bar 8 which extends outside of theframe on either side. At the rear end of the frame are placed thebrackets 9 and 10 which extend upwardly and rearwardly and support thecross bar 11 which extends outside of the frame on either side. At theforward end is provided the wheels 12 and 13 with an axle therefor and atongue 14 extending forward form the axle. At the rear is provided thewheels 15 and 16 and the axle 17 therefor.

On the front end of the frame is mounted the internal combustion engine18 by which the ygang plow is rotated. In front of this is provided theradiator 19 by which the engine is kept cool. From the engine leads rback the power shaft 20 having a ily wheel 21 thereon. On the shaft 2O afriction disk 22 is provided which makes contact with the frictionpinion 23 by which power is transmitted to the` jack shaft 24. A spring25 is placed around the shaft 2O and presses on a collar 26 which ispinned to the shaft by which the disk 22 is held in contact with thefriction pinion 23. The shaft 24 is provided with suitable bearings onthe sills 2 and 3. On the end of the shaft 24 is provided a sprocketwheel 27 which drives a chain 28 which in turn. drives a sprocket wheel29 on the shaft 30. rotate in suitable bearings provided on the crossbar 8. Y

The cross bar 8 is made up of two parallel I beams 33 and 34 that arefastened to the sills 2 and 3 and extend out beyond them on each sidethereof. On the ends of these I beams are provided the brackets 35 and36 which brackets extend down below the I beams. In these brackets theshaft 30 is mounted to rotate below the sills 2 and 3.

The short shaft 37 is mounted to rotate inthe sills above the shaft 3()and parallel thereto. Above the I beams 33 and 34 is provided the.drivers seat 31. Suitably mounted on the frame is the lever 32connected by links to the friction pinion 23 by which it may be movedfrom central position and out therefrom to vary the speed at which itwill be driven. The disk 22 is hollowed out at the center so that whenthe pinion 23 is placed in central position it will not make contactwith the disk 22, and will therefore not he driven but will stand idle.This permits the starting ofthe engin-e free from load after which ltheload can be placed thereon by shifting the pinion 23 for which purposethe lever 32 and connecting links are provided.

Below the drivers seatis mounted the foot pedal or lever 38 by which afriction drive is operated as follows: Splined on the shaft 37 is afriction disk 39 which is moved sidewise by the throwing of the pedal 38which disk then comes into contact with another disk keyed on the shaft30, both of which disks are located substantially below the driversseat. When these disks are brought together the lower shaft causes theupper shaft 37 to rotate through the disks. On the ends of the shaft 37are provided suitable drums 43'and 44 which rotate therewith and towhich are fastened cables 45 The shaft 30 is mounted Vto and 4:6. Thesecables pass backj civ-er pulleys 17 and 48 carri-ed on the brackets 9iand 10 down therefrom and are adaptedlt'o the swinging frame whichcarries therotating gang plow that will presently be dek scribed.

Near the outer ends of the shaft 30' are provided the sprocket lwheelsv5() `and`51 which rotate therewith as the shaft is driven by thesprocket wheel 29. These sprocket wheels are carriedl on sleeves 52 and53 which are provided with disks which4 make frictional Contact withAcluch members 54 and 55 which are keyed to the shaftso ast-o rotatetherewith. Ordinarily all parts rok tate together, but anwextra heavyloadcis thrown on the plows which preventswthem from rotating, such asstriking 'an obstruction as a stone, stump, etc., thesepfrictionclutch-es will slip andrvsave the mechanism from breaking. Otherwise the,frictional' Contact is sufficient to .secure positive drivlng i i .L

As above described the brackets35 and 36 containthe bearings in whichthe shaft 8O is supported and rotates. These brackets also are providedwith lugs ,G and in which are pivotally mounted the sills 66 and 67 ofthe swinging frame which sup? ports the gang plow. These sills areconnected together by the angle irons (i8 and 69, forward of the plow,andare connected together by the angle iron 70 behind the plow. To the`angle iron 68 is connected suitable eyebolts 71 to which the cables l5and 16 are'connected by which the fraineis lifted. Inthe frame areprovided suitable bearings 73 and .74 in vwhich, is joiiriialed theshaft 75 which is driven by the sprocket wheels 76 and ,77,which inturnaredriven the sprocket chains 7 8 and 79 from the sprocket wheels 50and 51.

On the shaft 75 are keyedvin pairs the disks S0 and 81 v,between whichthe standards 82, 82 are fastened. ,'Illiese-staiidards are fastened bya metal bolt or rivet 83 and a wooden pin S4 so that in case ythe `sharestrikes some obstruction in the ground that might break the machinerythe woode'nfp'iii 84 can break and release the standard 82 which canswing on the bolt 83.

On the outer end of thestandard 82 is fastened the share 85. As shown inFigure 3 the forward end of the standard i`s.provided with falug orshoulder Y86 and the standard is beveled at the rear end as shown at 87,the bevel being' filled up by the wedge 8S. The share is provided withal hub 92 having a socket :89 therein that willA receive theshouldered'en'd of tlielstandard 82. vAfter the share islinplacevtheivedge 88 is in-- serted and is drawn down by the screw 90which is threaded in the lug' 91` In this way the share is rigidlyfastened in place on the standard 82 and cannot work loose. The sharecomprises the hub 92 and the shank 93 extending forwardly therefrom to apoint o n top of which, afs shownin Figures 3 and 4, is` provided' ablade 94 which is welded or riveted to the shank.

As shown in Figure 2 four of these standards and shares are providedbetween each pair of disks and as shown in Figure 1 five pairs of disksareassembled on the shaft 75 all ofwhich rotate together and are drivenbyrpo'w'er from' the engine 18 for the purpose of digging up the groundthe plow is drawn forward' by thehorses. This machine is intended toplow a furrow about five feet wide at the rate of two miles or more lperhour.
